Printable Version: B-Sedan Challenge 17.02 (pdf)

The B-Sedan Challenge series is designed to celebrate the history of small-bore sedans. Small-bore production cars have been a mainstay in sports car racing and their popularity grew into one of the greatest series in American racing history, Trans-Am!

The goal of the series is to provide close competitive racing for small-bore sedans that competed from January 1966 to October 1979 in Trans-Am, SCCA B-Sedan and IMSA RS. Due to the time period, the numerous rule upgrades and speed enhancements that occurred throughout the original SCCA 2.5 Challenge, to B-sedan’s final years, adjustments have been made by the series officials of the B-Sedan Challenge to make all of the vehicles entered as competitive as possible, while adhering to the “Spirit of Vintage Racing,” in the hope of creating large competitive fields of cars. The goal is to have safe, close racing among all makes and models.

The B-Sedan Challenge is a nationwide series made up of multiple regions. There will be Regional and National Series Champions. For the 2018 season the National Series Championship race will be held at the US Vintage Racing National Championship at Circuit of The Americas (COTA) November 1-4. Each regional championship will be determined by points and awards given out at the Saturday night banquet at COTA. The B-Sedan Challenge National Championship winners will be crowned on Sunday. There will be a podium for 1st, 2nd and 3rd in finishing order and a 1st, 2nd and 3rd overall series points champion’s podium.

The B-Sedan Challenge series is open to all cars like those that competed in the 1966 to 1979 B-Sedan Trans-Am series including both the SCCA 2.5 and IMSA format. Two classes of cars will compete: Traditional B-Sedan cars, and B-Sedan Lite. The wording “2.5” was and is in place to open the series up to specific cars like Ford models which have 2.3 liter motors as stock equipment with the weight of the car corresponding to the nominal displacement of the engine, this is meant to equalize the field. For the complete original rules and a list of all eligible cars refer to the 1972-1979 SCCA GCR’s.

All rules in this document supersede any original or other set of rules where applied. For any odd engine or car specifications please contact the National Director for approval.

All vehicles are required to display the official B-Sedan Challenge windshield banner at the top of the windshield to be eligible for points. Each region will have a different logo in the left corner of the windshield banner. Series sponsor stickers may be required.
All cars will be weighed with the driver as they exiting the track post-race. To get an accurate weight add 185lbs for the driver to your specific cars minimum weight for the total minimum weight. Example; your cars minimum weight is 1800lbs, add 185 for driver weight for a total official weight of 1985lbs exiting the track. If you weigh more than 185lbs you may take weight out of your car if your total weight is more than your official minimum weight. Likewise if you weigh less than 185lbs you may need to add weight to your car to meet the official minimum weight.

Cars may be weighed at any time. Failure to comply with weigh-ins will result in disqualification of position, loss of session points and will start at the back of the field for the next session. Official event scales will be declared at the beginning of the weekend. The weight is the weight; there is no margin of error. The event scales reflect the final decision for weigh-ins.

Weights of cars not listed may be determined via written requests to the National Director.

Weight penalties may be assessed for minor car spec infractions.

All B-Sedan & B-Sedan Lite cars must be kept neat and clean at all times. Period paint schemes are encouraged as well as period advertising. A separate Presidents award will be given annually by SVRA for the car and team that most exemplifies the spirit of the B-Sedan series. The criteria of the award include hospitality of the team to fans and other drivers, paddock presentation, and professionalism.

B-Sedan Challange Series Competition & Conduct

The Regional Competition Director/s at any time during a season may use competition adjustments to even the field as he sees fit, these adjustments will carry over to the B-Sedan Challenge Championship weekend.

If a car is prepared beyond the spirit of any of the rules, the car may be disqualified at any time. All cars should be prepared and driven with the “Spirit of Vintage Racing” in mind. All competitors must maintain respect for directors, event officials and their fellow competitors on and off the track at all times. We are here to have fun first and foremost.

Any car infractions or unsportsmanlike conduct during the course of the season shall be dealt with by the regional directors and/or national director. Points may be deducted at director’s discretion.


B-Sedan & B-Sedan Lite Points System.

B-Sedan & B-Sedan Lite will maintain separate overall point standings for purposes of the season point’s championship.
Points will be awarded for finishing positions for 2 races per weekend as follows.
1st = 11 points
2nd = 10 points
3rd = 9 points
4th = 8 points
5th = 7 points
6th = 6 points
7th = 5 points
8th = 4 points
9th = 3 points
10th = 2 points
11th + 1 point

Points will be awarded for 2 Qualifying sessions per weekend as follows.

Points will be awarded for laps completed (rain or shine), 1 point per lap will be awarded based on laps completed as shown on the official event timing and scoring sheets, 8 laps maximum, If actual total Qualifying session laps are more or less than 8 a formula will be applied to equal the maximum 8 laps.

Example, a Qualifying session for whatever reason only has 6 laps; 8/6=1.333 points per lap. If you completed 4 of the 6 laps 4X1.333=5.333 points will be awarded. If a Qualifying session is called by the event directors (not regional directors) because of inclement weather all cars will receive 8 points. If a Race is called for the same reasons, points will be awarded for the best times in the previous qualifying session or, finishing position of the previous race.

There are 2 double regional races Sonoma and The Brickyard, drivers will score points based on their (in region) finishing position not overall finishing position.

The final regional race at COTA will be held on Saturday and will be a standard point’s race, it will count as the last regional race. The B-Sedan National Championship will be decided on Sunday and will be a double point’s race.

A Tie Breaker rule will be applied as follows:
1. Race Starts (Saturdays Qualifying Race is considered a race)
2. Race Laps Completed
3. Average of all Race Finishing Positions
4. Qualifying session points

NOTE: Drivers with any violation of any B/S Challenge prep rules, or being found underweight anytime during the season shall NOT be eligible for any tie breaker rule.

Drivers may attend events outside their local region for regional points as long as these events are supported by the B/S Challenge Series. (Please see the B/S Challenge schedule)

Any competitors that choose to race nationally instead of regionally may score national championship points at approved events but these points will not count toward a regional championship. This choice must be approved by the National Director prior to your first point’s race.

A maximum of 4 events will be scored including 1 out of region event. Competitors may score regional points at the first out of region event attended only. After a 5th race in or out of region the lowest scoring weekend event points will be dropped for the maximum number of 4 event weekends. Any official B/S Series events after the first five are not eligible for scoring points.

COTA will be the fifth point’s event for all regions and will include 2 Qualifying sessions and a Saturday B-Sedan race. The points scored at this event may not be dropped. The B-Sedan Championship race on Sunday and will be for double points.

All Drivers are responsible for emailing their highlighted, official, weekend time sheets / results to the National Director in order to score points.

Local regions are determined by the state in which you reside.
